Technical Information

Compact Linear Accelerator with Express™

The compact X-band linear accelerator emits circular beams with secondary collimation ranging from 5 mm to 60 mm. This compact lightweight system allows for precisely delivered pencil-shaped beams of radiation in almost any direction, providing superior conformality when treating patients.

Robotic Manipulator

The robotic manipulator used by the CyberKnife® System is made by Kuka™, one of the leading robot manufactures in the world. This high-precision robot is capable of delivering a repeatability accuracy of less than 0.2 mm.

X-Ray Sources

The low-energy x-ray sources generate two perpendicular, oblique diagnostic x-rays that determine the location of bony landmarks or implanted radiopaque markers throughout the entire treatment.

Image Detectors

The high-resolution image detectors capture x-ray images and generate digital images of the anatomy. These images which are taken throughout the treatment are compared to the digitally reconstructed radiographs (DRRs) generated from the CT scans used for treatment planning. The imaging system then determines the patient’s position and sends a command to the robotic manipulator to correct for movement.

Synchrony™Respiratory Tracking System

The Synchrony Respiratory Tracking System is the first technology in the world capable of delivering radiosurgery to targets that move with respiration. The CyberKnife® System synchronizes the Robotic Delivery System to the motion of the tumor so margins of less than a millimeter are needed in order to compensate for respiratory motions.
